Im wondering how to because whenever i leave my house,my bro-in-law goes though my comp looking for stuff. I want to lock my pc though the screensaver where i just put my password in to get in my PC.
In XP look in Display Properties, on the Screensaver tab, check the box that says "display welcome screen when resuming from screensaver" or something like that. That will toss you back to the login screen. That should be enough to keep a nosey bro-in-law out. If you aren't using XP, look in the same general area, there should be a similar setting for requiring a PW, I just forget where it is at the moment.
